A. The country that has lower real interest rates will experience a depreciation of their currency. This is because there will be a higher demand for the currency of the country that has higher interest rates.

B. The country that has a higher inflation rate will experience a depreciation of their currency relative to a country with a lower inflation rate. If Country A has a higher inflation rate, the currency of Country A will depreciate. This is because the inflation makes each unit of the currency less valuable.

C. A more restrictive monetary policy in Country B will cause economic growth in Country B to slow. This will cause people in Country B to purchase fewer imports from Country A. The decreased demand for Country A’s currency will cause Country A’s currency to depreciate relative to Country B’s currency, not to appreciate.

D. The increase in exports by Country A will lead to increased demand for Country A’s currency on currency markets (in order to purchase its exports). The increased demand for its currency will lead to appreciation of Country A’s currency.
